Other updates and bugfixes: - Tomcat 9.0.119: * Catalina + Add: Add support for literal '%' characters in access log output. Based on pull request #1002 by Fabian Hahn. (markt) + Fix: Prevent duplicate log messages when clustering JARs are not present on startup. (csutherl) + Code: Remove unnecessary code from the SSI processing engine that was duplicating some of the normalisation checks. (markt) + Fix: Cleaner handling of invalid SPNEGO tokens.

(remm) + Fix: Improve robustness on using Pipeline.setBasic on a running pipeline. (remm) + Fix: Avoid any init parameter updates when conflicts are found for filters, similar to what is done for servlets, as required by the servlet specification. (remm) + Fix: Fix container event cleanups in some edge cases. (remm) + Fix: Check for last-modified header in ExpiresFilter when a servlet uses addDateHeader to avoid wrongly considering it has been set. (remm) + Fix: Fix hour unit used by ExpiresFilter. (remm) + Fix: Remove exception swallowing in DataSourceStore to align itwith FileStore and avoid session loss on errors. (remm) + Fix: Add support for single-quote escaped literal as well as quoted literals in DateFormatCache. (schultz) + Fix: On JAAS logout, clear out role principals on the subject that were added on commit, as recommended by the JAAS specification. (remm) + Fix: MemoryRealm should not add a dummy role when none is specified in the configuration. (remm) + Fix: DataSourceUserDatabase should return a null principal on a non existing user. (remm) + Fix: Fix shared lock expiration in WebDAV. (remm) + Fix: Inaccurate session exipration statistics when using the persistent manager. (remm) + Fix: Skip BOM when serving files with UTF-32 encoding. (remm) + Fix: Mixup of WrapperListener and WrapperLifecycle elements in storeconfig. (remm) + Fix: Incorrect processing of modified users in DataSourceUserDatabase. (remm) + Update: Clarify behavior in the UserDatabase for user, role and group creation that it does not immediately override existing elements. Removal (or update) needs to be used instead. (remm) + Fix: 70049: Align the web application class loader with parent class loaders and swallow any errors caused by invalid paths when looking up resources and behave as if the resources were not found in that case. (markt) + Fix: Improve validation of Range and Content-Range parsers so invalid ranges trigger a 4xx response rather than a 500 response. Pull request #1012 provided by Sahana Surendra Bogar. (markt) + Fix: Fix connection leak in ProxyErrorReportValve. (remm) + Fix: When using the RewriteValve, %{SSL:HTTPS} now returns on or off rather than true or false to align with httpd. (markt) + Fix: Reset the encoding used for query string parameters between requests in case an application changed the encoding in a previous request. (markt) + Fix: When encoding URLs with the CsrfPreventionFilter, don't add thenonce to URLs that are known not to require it.

(remm) + Fix: Change the default for the useRedirect attribute of the ProxyErrorReportValve from true to false. (markt) + Add: Add support for the showReport attribute in JsonErrorReportValve and ProxyErrorReportValve. When set to false, detailed error information (message, description, stack trace) is suppressed from error responses. (dsoumis) + Fix: Avoid a NoClassDefFoundError at startup when catalina-tribes.jar is removed but catalina-ha.jar is present and the Cluster element is enabled in server.xml. Cluster digester rules are now fully conditional on both JARs being available. (dsoumis) + Fix: Fix a potential deadlock when copying resources using WebDAV. (markt) + Fix: Add jakarta., org.apache.catalina. and org.apache.tomcat.to the list of reserved prefixes for SSI variables and request attributes. (markt) + Fix: Missing URL decoding when processing addMapping on a Servlet registration. (remm) + Fix: The Timeout WebDAV header allows comma separated values (according to the examples in the RFC). Use the first acceptable value. (remm) + Fix: Fix various issues when logging the effective web.xml for a web application. Empty sections are no longer logged. Special roles and empty authorisation constraints are included. (markt) + Fix: Expand the write lock forthe save process in the MemoryUserDatabase to avoid concurrency issues with the file save operations. (markt) + Fix: Ensure atomic session persistence in FileStore. Based on pull request #1016 by sahvx655-wq.

(markt) + Fix: Ensure listeners are correctly added and removed when configuring the channel coordinator. (markt) + Fix: Fix some concurrency issues in FragmentationInterceptor. (markt) + Fix: Fix some concurrency issues in OrderInterceptor. (markt) + Fix: Fix some concurrency issues in TwoPhaseCommitInterceptor. (markt) + Fix: Fix concurrency issues generating MD5 digests in the CloudMembershipProvider implementations. (markt) + Add: Add replay protection to the EncryptInterceptor. This is a breaking change for the EncryptInterceptor. (markt) * Coyote + Add: Log a suitable warning if an encrypted PEM file is detected using an insecure form for encryption. (markt) + Fix: If TLS groups have been configured, use the configured groups rather than using OpenSSL's default TLS groups when using Tomcat Native with OpenSSL based connectors. (markt) + Fix: For HTTP/2, ensure that any in progress request body reads are cancelled if the container resets the associated stream. This prevents delays waiting for reads to time out when it is known that no more data will be received. (markt) + Fix: Ensure that malformed HTTP/2 messages that should trigger a stream reset do so, rather than triggered a connection close. (markt) + Fix: Improve enforcement of header trailer allow list for HTTP/2. (remm) + Fix: 70050: Avoid NPE when no header frame is processed in HTTP/2, following refactor clean-up of header buffer.

(remm) + Fix: 70091: Add a new attribute, allowSchemeMismatch to Http2Protocol that allows the consistency check for the scheme provided by the user agent to be bypassed. (markt) + Fix: isTrailerFieldsReady was always returning true. (remm) + Fix: Align OpenSSL/Panama TLS implementation with other implementations and throw an exception if there is an error loading the provided CRL(s). (markt) + Fix: Parsing of OpenSSL format cipher expressions incorrectly stopped if @STRENGTH was encountered, ignoring any subsequent expressions. (markt) + Fix: Handle the case where the HTTP/2 payload length is insufficient for the mandatory data required by the flags set in the header. (markt) + Fix: 70102: Correct expected size of ticket keys when calling setSessionTicketKeys with an FFM connector. (markt) + Fix: 69988: Fix post handshake authentication for TLS 1.3. It was broken by a breaking change in OpenSSL between 1.1.1 and 3.0.0. (markt) + Fix: When processing an OpenSSL cipher specification, fully align the order of the resulting ciphers with the order produced by OpenSSL. (markt) + Add: Add support for Brainpool TLS groups. Patch provided by YStankov. (schultz) + Update: Update both the minimum and recommended version for Tomcat Native 1.x to 1.3.8. (markt) * Jasper + Fix: Fix possible EL argument mismatch when it was set to null. (remm) + Fix: Fix thread safety of TagPluginManager. (remm) + Fix: Correctly use flush on JSP include.
